IMPROVEMENT IN SOLDERlNG-MACHINES.

Specification forming part of Letters Patent No. 139,763, dated June 10,1873 application filed May 20, 1873- l To all whom it may concern:

Be it known that I, WIL IAM D. BROOKS, of Baltimore city and State of Maryland, have invented a new and Improved Soldering Apparatus; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification.

The invention relates to means whereby the intense heat of the blow-pipes is prevented from coming into close proximity with the can by an intermediate rotary soldering-tool; also, peculiarities of construction in the soldering-tool; and also to a novel mode of constructin g the bolt which couples together the sections which embrace the water, gas, and

air chambers, all as hereinafter described and "pointed out in the claim. The invention also relates to a novel mode of constructing a rotary tool, intended to solder a cap to the body of a can withput wasting the solder and smearin g it on cap or head. It also relates to a method of constructing and putting together the gas and air chambers, so that they can be readily separated in order to substitute larger or smaller burners.

In the drawings, Figures 1 of each sheet of drawing are vertical sectional elevations,

Figs. 2 and 3, horizontal sections of the soldering-iron.

In sheet 1 of drawings, A represents a can placed in position to have a head soldered to the body. B is the cap-holder, attached to its lift-tube b; and O is the circle of burners or blow-pipes that heat and liquefy the solder.

D is a soldering-too], placed loosely on the lift-tube b, and keyed to the tube by a pin, d,

- that plays in a slot, 6, of the fast collar E. By

this mode of attaching the soldering-tool to the lifter-tube b, which is rotated bya pinion, b the tool has end play enough to enable it to adjust itselfto thetop of the can, while it is also compelled to rotate with the tube b.

The soldering-tool D has an annular trough, al connected by perforations d with the recess (1, through which the melted solder passes into the seam between the topedge of body and head. The shape of the recess d is of straight down into theseam,;while the cit cumjacent lip d embraces the edge of can,

and shuts out such air inpouring of air as would tend to cool and stitfen the solder before it had been properly distributed. By interposing thetool 1) between the blow-pipes and the can, the intense'heatisless liable to injure the cainnietal. d is a series of holes that admit air to the inner surface of can-top. This air isheated and passes out of the tube 11. F is thetube in which the wire-solder is cut off, and through which the bits 'are dropped into thetrough 01 G is the gas and H the air-chambers, with their respective pipes g h. I is the water-chamber, and J the bolt by which they are attached together.

This bolt has the plate J provided near its edge with two opposite flanges, j j, on the lower one of which screws the gas-chamber Gr, While against the upper, and in the recess formed with the outer edge of plate J, is fitted snugly the circular edge of the air-chamber, which is in the same piece with the water chamber. The latter two chambers are held by the screw-connection of the bolt with the center of water-chamber. A collar, serves to prevent the weight of soldering-tool and connections from coming upon the can, and

thus interfering with the rotation of the tool.' a

The operation of the machine is as follows The cans are brought up under the soldering apparatus, when the cap-holder B first comes down and holds the cap and top in place while the soldering-tool D is revolved. The wire is cut oif in tube F, and dropped in trough d in which it is instantaneously melted by the intense heat of the blow-pipe. The fluid now passes do n through perforations d, and flows down into the seam which, in practice, is f rst fiuxedwith resin or equivalent. The soldering-tool is then raised, a full draft of air admitted, and the solder all'owed to set before the holder B is removed.

In sheet 2 of thejdrawing, A is the can B,

the cap-holder, having lift-tube b,- and (J, the soldering-tool, having trough c, perforations c 0 and inner projecting flange 0 This solderingtool is especially adapted and intended for putting on the cap D of a can, on each of which a channel, (1, is formed, as shown in Fig. l of the drawing. Into this channel d, and against the inner side thereof, passes the inner flange c of the solderingtool. As the bits of solder are cut in and discharged from the bent tube E, they are melted by the blow-pipes F in the trough c, from whence they pass through the perforations into the channels d of can.

By this construction there is no danger, or indeed any possibility, of the liquid-solder becoming smeared on the head of can or on the cap itself.

G is the gas and H the air-chamber formed in two pieces, 1 I and K K. The tube K is threaded, and Works in a thread, I, of piece 1. This construction is extremely simple, and allows the circles of different-sized burners to be changed with facility.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A soldering-tool having the pin 01 and loosely surrounding the revolving tube b, combined, as described, with a fast collar, E, having the slot 0, to enable the said, tool to. have end play and yet to revolve with the tube.

2. The combination, with one or more blowpipe burners, G, of a rotary soldering-tool havin trou h d and erforations d as and a a p 7 for the purpose set forth.

3. The flange (1 applied to the bottom edge of a soldering-tool to prevent the ingress of too much air before the melted solder has,

been properly distributed.

4. A soldering-tool having the oblique face d in connection with the perforations 01 as and for the purpose set forth.

5. The bolt J, having a disk, J, with flanges j j that enable the sections to be coupled together in the manner described.
